Using a commercial STED microscope and restricting imaging to smaller field of views allowed STED imaging at a frame rate of 0.4 to 0.8 Hz (Supplementary Videos 5 and 6). Because Nile Red can be effectively depleted using far-red depletion lasers (here λ dep = 775 nm), it can be combined with other membrane permeable labels, for example, live-cell compatible SiR-conjugates. Here, we demonstrate confocal and STED microscopy with short, fluorophore-labeled oligonucleotides that transiently bind to complementary oligonucleotides attached to protein-specific antibodies. The constant exchange of fluorophore labels in DNA-based STED imaging bypasses photobleaching that occurs with covalent labels. STED imaging now overcomes this limitation and permits studying the fine structure of spines in living tissue. Fig. 4 illustrates the types of structural changes that can be observed by STED imaging.

Superresolution microscopy using stimulated emission depletion (STED) creates sub-diffraction limit features by altering the effective point spread function of the excitation beam using a second laser that suppresses fluorescence emission from fluorophores located away from the center of excitation. 15 hours ago STED microscopy allows super-resolution imaging in the 50nm range. Unfortunately, this increased optical resolution also leads to a drawback: because many fluorophores are depleted by the depletion laser, this also results in a lower signal (fewer photons) being captured by the detector.

19 May 2020 Stimulated emission depletion (STED) microscopy does not suffer from these shortcomings despite having a lower axial resolution (20). Besides,

Similarly, the performance of the system may be limited by the sample itself. Optimization of the STED parameters taking into account the sample itself is therefore a complex task as there is no clear methodology that can determine the image improvement in an 2012-08-15 · Imaging and physiology data were acquired using data acquisition boards (National Instruments, Austin, TX) and modiﬁed versions of the software ScanImage (14) with code written in MATLAB (The MathWorks, Natick, MA). STED laser powers were measured at the output of the microscope objective. Live neuron imaging was performed with a time-averaged Christian Eggeling Group in Jena Biophysical Imaging Lab - Super-resolution microscopy and membrane biophysics.

In contrast, stochastic optical reconstruction microscopy ( STORM ), as performed using Nikon's N-STORM system, is a single-molecule approach that relies on activation of a limited subset of the overall molecular population to sequentially image and localize individual emitters on a 2020-03-01 2017-02-28 2008-12-02 2019-09-30 Using a commercial STED microscope and restricting imaging to smaller field of views allowed STED imaging at a frame rate of 0.4 to 0.8 Hz (Supplementary Videos 5 and 6).

It creates super-resolution images by the selective deactivation of fluorophores, minimizing the area of illumination at the focal point, and thus enhancing the achievable resolution for a given system. Stimulated Emission Depletion Microscopy (STED) Imaging below the optical diffraction limit Stimulated emission depletion microscopy (STED) is a fluorescence microscopy technique that overcomes the diffraction limited resolution of confocal microscopes. This adjustable, super resolution system performs four-color, live-cell 3D imaging at the nanoscale in real time. The STED microscope was selected following a multi-week, hands-on evaluation and feedback from users on both the Leica STED-3X and the Abberior easy3D STED.

Lifetime imaging and advanced time-gating. Pulsed high-power STED lasers for best resolutions with 2D and 3D superresolution nanoscopy; Detectors with superior detection efficiency (up to 65%) Dual-color STED imaging with spectral discrimination has been shown earlier . Since, from those experiments, our STED microscope was pre-equipped for two-color operation we were able to combine lifetime and spectral separation to perform three-channel STED imaging with resolution not fundamentally limited by diffraction.

Imaging dendritic spines in the hippocampus in vivo is challenging because of its remote location more than 1 mm below the surface of the mouse brain. A pioneering study accomplished this with two-photon (2P) microscopy, but only over a period of a few hours (Mizrahi et al., 2004). Super-resolution imaging using the principles of stimulated emission depletion (STED) microscopy requires collinear excitation of a sample with a Gaussian-shaped excitation beam and a donut-shaped depletion beam whose spin (polarization) and orbital angular momentum (OAM) signs are aligned. STED is a fluorescence microscopy technique which uses a combination of light pulses to induce fluorescence in a small sub-population of fluorescent molecules in a sample. Each molecule produces a diffraction-limited spot of light in the image, and the centre of each of these spots corresponds to the location of the molecule.
